Bitcoin (BTC) is a decentralized digital currency that operates on a peer-to-peer network without a central authority. It was created in 2009 by an anonymous entity known as Satoshi Nakamoto. BTC transactions are verified through blockchain technology, ensuring transparency and security. Unlike traditional currencies, Bitcoin has a fixed supply of 21 million coins, making it a deflationary asset. It is widely used for investment, remittances, and online purchases. Bitcoin's value fluctuates based on market demand and adoption. Many see it as "digital gold" due to its store of value properties.
